Posted 9 Aug 2009 by Copycat-Digital for WCG*
Post:
The current small WUs (ps_82test) are causing the WU shortage because it is increasing the network traffic. This happened not so long ago (MW WUs was as scarce as rocking horse poo) and was corrected by increasing the WU length because the ATI app. crunch a WU in no time.
Experience normally prevents someone not to make the same mistake again!
3) Message boards : Number crunching : ATI GPU app 0.19f fixes the ps_sgr_208_3s errors (Message 28477)

Post:
ATI GPU app 0.19f is always running "high priority"
This causes that the CPU app running on the same PC is limited to only 2 cores
I tries to fix it with "<cmdline>n1</cmdline>"
Only the number of CPUs specified in <cmdline>n(x)</cmdline> runs active while 18 WUs show that they are running but is waiting for a GPU
Im running boinc 5.4.7 and tried 6.6.36 with no luck
Is there a fix for this?

Win XP Pro (32) sp3
CPU = Q8200 quad
4 Gb memory
1 x ATI 4500 (Cat 812)
Boinc 5.4.7

Travis must be working on it - who knows when we'll see it ;P


June 11, 2009
Travis here. I'm going to be camping until Sunday so don't break anything while I'm gone. Hopefully Matt and John will keep the server running and filled with work for you guys :) I'm still having a few problems with the CUDA application for regular milkyway, so it'll probably be out Monday or Tuesday after I get back.


Still camping.
Maybe someone should send a search party :)

"....and with a full cache of 64 x 6 workunits in progress!"

thats wrong - you can only get up to 48 WUs even if you got more than 8 CPUs/Cores etc


You are quite right - I only looked at the first 2 pages.
The computers are visible here

But who would put vista on a server?!
Actually, who would put vista on anything? :)


I have a friend - a builder - he used run it on his concrete mixer but then he discovered that mixing concrete with man-power is quicker and produce a better quality concrete :)
PS He tried a demo/beta of Win7 but it only works if he replaces the 2 cylinder engine with a V8

A server possibly?


OK a motherboard with 16 Q6600 CPUs - but what is the then:

"GenuineIntel
Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz [Intel64 Family 6 Model 23 Stepping 6]
(64 processors) Microsoft Windows Vista
Ultimate x64 Edition, Service Pack 2, v.275, (06.00.6002.00) 20 May 2009 20:01:38 UTC"

32 Core 2 Duo CPUs in 1 server?

I noticed an user running 8 hosts. 5 Hosts reports 64 CPUs with Vista X64 - and with a full cache of 64 x 6 workunits in progress!
How is this possible?

Example:

"GenuineIntel
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz [Intel64 Family 6 Model 15 Stepping 11]
(64 processors) NVIDIA GeForce GTX 260 (896MB) Microsoft Windows Vista

Can't keep the ATIs cool!

Thanx Travis!

Even with the fixed ATI app, I'm still getting errors on the 3s work.

11) Message boards : Number crunching : Work Availability? (Message 24080)
Posted 3 Jun 2009 by Copycat-Digital for WCG*
Post:
Keep in mind 3 things happened:

1) There was a minor server outage

2) The request was changed from 6 to 60 seconds

3) The very small ps_sgr_208_* runs

My humble opinion is that the "ps_sgr_208_*" runs is the culprit causing an increase to the network traffic because of its very short run-time

I'm working on it. Hopefully WUs will be availalble at milkyway_gpu@home sometime this week.


I hope the 6 WUs per cpu will go away at milkyway_gpu@home
At the moment an i7 with a 4830 does more work than a Core 2 Duo with a 4870 - speed does not count but the bigger cache of WUs the i7 receive makes a big difference

Scheduler list received back after request OK till yesterday when the server went down. No scheduler list master file return received since last night.
Trying manual update without response from server and get sometimes: Internet access OK. Server may be down.
Scheduler list from SETI, CPDN & WCG running normally so it can't be my link.

Post:
I think that we all overlooking the fact that work units are allocated 6 per cpu- core. This is totally irrelevant to the crunching capacity of your GPU.
So you can script or manually refresh till you are blue in the face.
A 3850 installed in an i7 will earn more than a 4890 in a dual because the i7 will get 48 work units and the dual only 12

Nothing new then :/

Only news is the ongoing fight who should get the biggest slice of the pizza.
I look like BOINC cut down on the amount Cr's MW can hand out if you look at this graph
